StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors Product Line

The StopTech Sport Cross-Drilled & Slotted Disc Brake Rotors line is developed to provide enhanced braking performance for street and light track applications. This product line combines cross-drilled holes and precision slots to improve pad bite and help evacuate gases, dust, and water from the rotor surface. The vented rotor design further aids in heat dissipation, making these rotors suitable for Ford Mustang drivers who demand consistent braking under varied driving conditions.

Applications and Problem Solving

• Reduces brake fade during spirited driving or track sessions
• Improves wet weather braking by channeling water away from the rotor surface
• Minimizes brake dust buildup for cleaner rotor and pad contact
• Helps prevent rotor warping through improved heat dissipation
• Restores braking performance on Ford Mustang models requiring 380 mm rotors

Installation Notes and Tips

• Compatible with Ford Mustang models requiring 380 mm vented rotors with 5 lug holes and 114.3 mm bolt circle diameter
• Ensure rotor discard thickness is checked regularly; replace when below 31.6 mm
• Hat finish is coated to resist corrosion; avoid abrasive cleaning methods
• Floating disc mounting requires proper torque specifications to prevent rotor misalignment
• ABS tone ring is not included; verify vehicle requirements before installation
